Priced 10-13 you have to strike. Positive comprehensive accessories like wrist strap, head mount, bike mount and spacer to use with 18650 lithium-ion batteries. A clip for attaching to a belt is also integrated in the lamp. The lamp can also be normal (2 hours of light in constant full brightness) or AAA batteries AAA batteries (hold 1.5 hours at 800mAh) operated (it each 3 Cellen needed). I use a 18650 battery with 2400 mAh, it is lit so that 2 hours at full brightness without losing brightness, after which it is then slowly dark. Positive, a focus ring, the spot can be adjusted, which is more of a rarity in LED lamps. Waterproof lamp is not because the lamp head has by design no seal, who is already a lamp into the water, I do not. Now for the thickness, the specified 500 lumen can not be reached, there are about 180 lumens at realistic. There is a Cree XPE Q5-LED installed, which works with 3 Watt 700mA and pulls, thus 180 lumens can be achieved. This could be seen as a defect, but on the other hand, would be at 500 lumens the batteries after 45 minutes empty (which would be insufficient), and 180 lumens rich in this size entirely from (for 13 will be no real get 500 lumens). The headlight range is about 100 meters, sounds little, but meant the actual distance is when you can see it all over, for the reflector size is a good value. There is also a dimming level (can be selected via the button in the end cap) with approximately 60 lumens about 1/3 of the maximum brightness. For self-defense in emergency situations even a stroboscopic flash with 180 lumens is (also via the button in the end cap can be selected) available. All in all, a well-made lamp (no sharp edges) at a reasonable price. It is handy, lightweight (only 156 grams with 3 AAA Eneloop batteries), not too big (133mm long, 35mm diameter, fits in your pocket), and therefore versatile. I can see the light (even if the promised 500 lumens are not achieved) only recommend.
